Viruses are:
A) infectious agents that infect multi-cellular organisms
B) noncellular particles that take over the metabolism of a cell to generate more virus particles
C) pathogens that replicate in complex growth media
D) cellular particles that belong to the archaea domain
E) microbes that consist of lipid membrane enclosed genomes

Question

Quizplus · Accepted Answer

Viruses are noncellular particles that require a host cell to replicate, and they use the host cell's metabolic machinery to generate more virus particles. They are not infectious agents that infect multi-cellular organisms, pathogens that replicate in complex growth media, or cellular particles that belong to the archaea domain. While some viruses have a lipid membrane envelope, not all viruses consist of such an enclosure.
